curl -u和python请求之间有区别吗

维塔利克·布什维（Vitalik Bushaev）

所以有一个我想翻阅的网页 python.Requests

需要基本身份验证。如果我像这样卷曲

 curl -u [email protected]:password https://ororo.tv/api/v2/episodes/9

但是，当尝试在带有Requests库的python中执行相同操作时，我得到了想要的响应，像这样

>>> r = requests.get('https://ororo.tv/api/v2/episodes/9', auth=('[email protected]', 'password'))
>>> r
<Response [520]>

我总是得到520响应。有人可以告诉我，我可能做错了什么？

是的，有细微的差异。在发送的标头中存在细微的差异，这些差异显然与此API有关。

如果更改查询使用的URL http://httpbin.org/get（在线HTTP测试服务HTTPBin.org的端点，则可以看到两者之间的差异curl并requests发送：

$ curl -u [email protected]:password http://httpbin.org/get
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
    "Host": "httpbin.org",
    "User-Agent": "curl/7.51.0"
  },
  "origin": "84.92.98.170",
  "url": "http://httpbin.org/get"
}
$ python -c "import requests; print(requests.get('http://httpbin.org/get', auth=('[email protected]', 'password')).text)"
{
  "args": {},
  "headers": {
    "Accept": "*/*",
    "Accept-Encoding": "gzip, deflate",
    "Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
    "Host": "httpbin.org",
    "User-Agent": "python-requests/2.11.1"
  },
  "origin": "84.92.98.170",
  "url": "http://httpbin.org/get"
}

要突出区别：

requests发送一个额外的标头Accept-Encoding，设置为gzip, deflate
的User-Agent报头的不同; 两者都反映了当前的代理商。

您必须在网站上查看这些标题中的哪一个导致了该问题https://ororo.tv/api/v2。当我像命令一样更正要使用的URLv2和并设置标题时，我得到一个有效的响应：httpscurlUser-Agent

>>> headers = {'User-Agent': 'curl/7.51.0'}
>>> r = requests.get('https://ororo.tv/api/v1/episodes/9',
                     auth=('[email protected]', 'password'), headers=headers)
>>> r
<Response [200]>
>>> from pprint import pprint
>>> pprint(r.json())
